Abstract

The response of neurons is highly sensitive to the stimulus. The stimulus can be associated with a direct injection in vitro experimentation (e.g., time dependent and independent inputs); or post-synaptic potentials resulting from the interaction of many neurons. A typical incoming stimulus resembles a noise which in principle can be described as a random variable. In computational neuroscience, the noise has been extensively studied for different setups. In this study, we investigate the effect of noisy inputs in a minimal network of two identical leaky integrate-and-fire (LIF) neurons interacting with finite pulses. In particular, we consider a Gaussian white noise as a standard function for stochastic modelling of neurons, while taking into account the pulse width as an elementary component for the signal transmission. By exploring the role of noise and finite pulses, the two neurons show a synchronous spiking behaviour characterized by fluctuations in the interspike intervals. Above some critical values the synchronous regime collapses onto asynchronous dynamics. The abrupt change in such dynamics is accompanied by a hysteresis, i.e., the coexistence of synchronous and asynchronous firing behaviour.

Abstract

Introduction: Tibial fracture is one of the most common injuries. Randu honey has the potential to speed up fracture healing. This study aims to determine the efficacy of randu honey supplementation on callus formation in closed fractures of the tibia in Wistar rats. Methods: This research uses a true experimental design with post test only control group design. A total of 36 Wistar rats were divided into two groups, namely the control group and the treatment group which were given 200g/BW(gram)/day of randu honey. Fractures were made on the rat tibia and callus diameter was measured at 3 weeks after treatment. Results: The callus diameter in the treatment group was significantly larger than the control group (p<0.05) in radiological and macroscopic measurements. Conclusion: Supplementation with randu honey is effective in the formation of callus in closed fractures of the tibia in Wistar rats.

Abstract

Abstrak Computational thinking adalah kemapuan berpikir sistematis yang mengintegrasikan proses logis, analitis, dan kreatif untuk menyelesaikan masalah kompleks. Penelitian ini bertujuan untuk mendeksripsikan kemampuan computational thinking siswa ditinjau dari tingkat self-efficacy. Penelitian ini merupakan penelitian kualitatif deskiptif. Subjek dari penelitian ini adalah 33 siswa kelas VIII yang diberikan tes angket self-efficacy. Selanjutnya, akan dipilih sebanyak 9 siswa untuk mengerjakan tes computational thinking dengan pembagian 3 siswa self-efficacy rendah, 3 siswa self-efficacy sedang, dan 3 siswa self-efficacy­ tinggi.  instrumen penelitian yang digunakan berupa angket self-efficacy, tes uraian, dan wawancara. Analisis data yang digunakan mengacu pada model analisis Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan terdapat 8 siswa dengan self-efficacy tinggi, 15 siswa dengan self-efficacy sedang, dan 10 siswa dengan self-efficacy rendah. Siswa dengan tingkat self-efficacy tinggi mampu memenuhi 4 aspek kemampuan computational thinking, siswa dengan tingkat self-efficacy sedang mampu memenuhi 3 aspek kemampuan computational thinking, dan siswa dengan tingkat ­self-efficacy rendah mampu memenuhi 2 aspek kemampuan computational thinking. Kata kunci:  computational thinking, self-efficacy, pola bilangan   Abstract Computational thinking is the ability to think systematically by integrating logical, analytical, and creative processes to solve complex problems. This study aims to describe students' computational thinking abilities in terms of their level of self-efficacy. The research is a descriptive qualitative study. The subjects of this study were 33 eighth-grade students who were given a self-efficacy questionnaire. Subsequently, 9 students were selected to take a computational thinking test, consisting of 3 students with low self-efficacy, 3 students with moderate self-efficacy, and 3 students with high self-efficacy. The research instruments used included a self-efficacy questionnaire, open-ended tests, and interviews. Data analysis referred to the Miles and Huberman model, which includes data reduction, data display, and conclusion drawing. The results showed that 8 students had high self-efficacy, 15 students had moderate self-efficacy, and 10 students had low self-efficacy. Students with high self-efficacy were able to fulfill all four aspects of computational thinking, students with moderate self-efficacy fulfilled three aspects, and students with low self-efficacy fulfilled two aspects of computational thinking.  Keywords: computational thinking, self-efficacy, number pattern

Abstract

An urgent issue related to national identity is the promotion of religious moderation, a responsibility shared by all sectors of society. Religious moderation should not be confined to religious education alone, but rather be embedded across all academic disciplines, including mathematics. This study investigates the trends of religious moderation within mathematics education research between 2019 and 2025, employing the bibliometric analysis method. The review focuses on mathematical content, research methodologies, levels of implementation, and country. Data for the study were sourced from Google Scholar, ScienceDirect and Dimensions AI databases. The selected publications were screened using the Systematic Review Accelerator and mapped through the PRISMA framework, based on predefined inclusion criteria. There are 14 (fourteen) articles assessed. Analytical tools included VOSviewer 1.6.20, RStudio-2024.09.0-375, and Microsoft Excel 365. The results reveal two key findings: (1) the concept of fractions is the most frequently associated with religious moderation practices in mathematics classroom, (2) The predominant approach employed by scholars to examine the incorporation of religious moderation in mathematical education is library research, and (3) the integration of religious moderation into mathematics education is primarily observed at the elementary level and is largely limited to the Indonesian context. Therefore, efforts to incorporate religious moderation into mathematics teaching should be expanded across all levels of education.
